Abstract
In shallow rivers that are enriched with nutrients, considerable amount of periphytons grow on the surface of stone and other material in river bed. This periphytons contribute to the increase in organic matters, because they slough continuously to the river water. For the precise estimation of water quality of above river condition, the rate of production of organic matters is to be determined.
In the study, the material balance of organics was determined by the experimental stream by means of the dissolved oxygen balance method proposed by H. T. Odum and the experimental results were compared with the calculated results.
According to this work the dissolved oxygen balance method was proved to be reasonable method for the estimation of the material balance of organics in the experimental stream.
